This carb won't idle worth a darn.
I'm aware that not having a correct 270 carb isn't a great start.
Where would you guys go from here? Thanks! Dave
You have really answered your own question. There are MANY differences in the Zeniths used on a 228 and a 270 other than the main venturi.
Find someone with a 228 that might want your Zenith, and look for the correct size.
